Well, I am "upgrading" (read: basically building a computer from the ground up) an AT based system. I never figured that my keyboard and mouse wouldn't fit into an ATX mobo, but there is clearly no slot for the keyboard and none for the mouse, except for two slots that would fit, but they don't have a mouse icon. Is there an adapter I can buy for one/both or do I have to buy all new peripherals? Thanks for any comments.
